Considering that the identifications can be very subtle, the question arises how to properly perceive whether we operate from the space of truth or from the illusory person’s space? Is there any interest in the action and how it can be most easily detected?
It’s easiest to detect it through emotions.
As I have already mentioned, every person within the space of belief constrains some energy potential. If belief in an idea is great and strong, then the person / believer will find it easier to realize the idea he believes. A person who, casually, believes in something, or changes beliefs very fast, will hardly materialized imagined. It has been shown in practice sometimes, that imaginative ideas have never been realized, regardless of the amount of energy invested. If an energy through faith is invested, and it is not realized, or there is a danger that it will not be realized, an emotional reaction occurs. The intensity of reaction is just proportional to the faith (energy) invested in the idea. Fanatical football fans will be disappointed if their club loses the game, while the average fan will have a lesser reaction to discomfort or something like that. The one who does not follow the football at all, will not have any reaction because he does not even know that the game is playing. There is no interest at all.
Another example. The mother desperately wants her daughter to finish her medical faculty and become a doctor. It is an idea in which she has invested a lot of faith, time and effort. The daughter, on the other hand, goes to medicine just to please her mother, because medicine is not something that she really like. She is interested in art. If a daughter graduate in medicine, mother will be the happiest person in the world. The daughter will be happy because of her mother, but she is not happy because she doesn’t like medicine.
If a daughter leaves the college, the mother will experience an emotional shock whose strength will be the same as the energy invested in her wish. The daughter will be a bit nervous because she let down her mother, but on the other hand happy because she left what she does not want to study.
The seriousness of the person is a good indicator of whether it acts through the mind content. If someone takes something very seriously (order, work, and discipline), the one certainly works through its convictions. The bigger that conviction is, the seriousness also becomes bigger, because there is a fear for a failure of investment. The conscious man is the one who acts unconditionally, therefore easily, I dare to say frivolously because he is not burdened by the result of action. Anyone who tells you that life is not a game, and that it needs to be taken seriously, speaks it as a person, from the place of its belief.

Each mind has one or two dominant personalities that it relies on, because it trusts them most. If you’re a good woodman, but you play a good trumpet too, if you lose your woodwork job you can always make some success, or at least survive by playing the trumpet. If that backbone collapse too, the identity is disturbed and the mind loses its ground. Since it is no good in any other thing and there is no faith in oneself, it may happen that the mind completely crumbles because of the loss of identity. This can easily happen in people with a borderline personality disorder.
It is quite difficult to excite calm and sedate people about something, but also to frighten them. They have a firm ego. The weaker ego, with no confidence, has much greater emotional oscillations. Perhaps you as a child had a dominant father (authority) who punished disobedience, and you were scared of him. If you are constantly indoctrinated that you must be obedient to authority, and that hierarchy is the necessity of our world, the mind then forms the general conclusion that all authorities are dominant and it is dangerous to oppose them. Moreover, in the mind, it becomes a normal world order. When such a mind later in life meets a policeman, a judge or a priest (the authorities), he will not oppose to any command that “authority” demands from him, because of fear. Maybe he’ll be a bit annoyed, but not a lot. If at least success to penetrate a little bit through fear and questions the police officer’s authority, that will be euphoric experience for that mind. The greater fear is, the euphoria of overcoming it is greater. Every time you want to counteract any form and pattern in which you are enslaved, fear appears, because you are acting with consciousness that is contrary to your beliefs. There is an energetically collision. Such a collision causes fear of the loss of belief (believer), and it is automatically defended by fear or some other “lower” emotion. This mind-resistance in the form of emotion is a mechanical reaction. Because of the lack of consciousness about the nature of emotional activity, it is perfectly normal that it is run autonomously as long as consciousness does not take control. In addition, consciousness identified with the mind does not allow the examination of the authenticity of the mind and tries to block every search for truth using the emotions.
In moments when you seek out the truth beyond the mind, attacks are happening. Attacks comes from your personal, inner space, or from people outside, who feels you want to get out and thus it activate their fears.
Emotions that occur in those moments are not real! If we believe in them, we get back to the world of mind, struggle, condemnation, etc.

To finally overthrow the illusion of a person and its emotionality, it is necessary to gather courage and enter into discomfort space. Regardless of your discomfort, emotion cannot do anything to you because there is no contact with your true being.

So in the end every fear, is actually fear of death. Fear is generated by believe in a person because a person is the only one who can die. I don’t want that you think that everything is bad, because good and positive emotions or even euphoric emotions are not excluded from this. They have much less and shorter durations. They appear when we have achieved the desired or when our interest is fulfilled. If the interest is greater pleasure is greater, but it should be recognized as conditioned emotion, not the true sense of satisfaction and happiness. You will easily recognize it, because it lasts quite a short period of time.

Many people perceive themselves as emotional beings. They do not look at themselves as mental entities, because they realize that thought is fluid (and is not), but the emotions are perceived as real, because there is bodily expression of it. That is true, but what they do not know is that this condition entirely depends on belief, and so it is false because it does not exist by itself (autonomously).

“… In this process we begin to understand a series of bad consequences of negative emotions and sensations. “Negative emotions” mean all the violent depressive feelings of self-pity, anger, suspicion, fear, rage, boredom, distrust, jealousy, etc. Such expression of negative feelings is usually accepted as something normal and natural and even necessary. But we have to be aware that this condition is conditioned. The condition that is created in us from external and internal factors. The worst thing is to call such emotions “sincerity”. Of course, this has nothing to do with sincerity. This palette of feeling is merely a sign of man’s weakness, bad nature, and inability to hold his or her own problems and resolve them. It is even a sign of intentional or unintentional feed from others through a variety of reactions, from pity to alleged help or counseling, which of course does not help, since the primary negative features are based on the fantasy and lying that came out from the complete ignorance about yourself.”
